SEOs do not appear in plan view for any elements except multi-plane roofs, morphs and shells - because these are the only 3 elements that use a top down 3D projection for their 2D plan view.
All other elements (slabs, walls, objects, etc.) 2D symbolic view that is not based on the actual 3D view.
Any reason why you need a slab object?
Why not use a composite slab and cut an actual hole in it with the pet palette (i.e. not an SEO).
